When it comes to Jeep U1159 code, there are many causes and solutions available to diagnose and resolve the problem. The Jeep U1159 code is a diagnostic trouble code (DTC) that indicates the loss of communication between the Automatic Sway Bar System (ASBS) module and the Totally Integrated Power Module (TIPM). This code is triggered when the Ignition Off Draw (IOD) fuse is installed, and voltage ranges between 10 and 16 volts with the ignition on. The Jeep U1159 code can be caused by a number of underlying issues, such as a shorted CAN C bus circuit, DTCs related to battery voltage, ignition or VIN messages, TIPM not configured correctly, or an issue with the ASBS module power and ground. To fix the issue, it is important to identify the root cause and then take the necessary steps to resolve the problem.
